TOBACCO-PIPE.

Specification forming part of Letters Patent No. 50,127, dated September26, 1865.

To all whom it may concern:

Be it known that I, EDWIN Hovr, of Stem ford, in the county of Fairfieldand State of Connecticut, have invented a new and useful Improvement inSmoking-Pipes; and I do hereby delare that the followingis a full,clear, and exact description thereof, which will enable others skilledin the art to make and use the same, reference being had to theaccompanying drawings, forming a part of this specification, in which--Figure 1 is a vertical central section of the bowl ofa tobacco-pipe,showing my invention applied thereto. Fig. 2 is a top view of myinvention.

Similar letters of reference indicate like parts.

My invention consists in the employment or use, in a pipe having anicotine-chamber below the bowl thereof, of a perforated disk ordiaphragm arranged below the smoke passage from the bowl to the stem insuch manner that the smoke will come in contact with the said disk ordiaphragm, and thus be caused to deposit the nicotine it may containwithout passing through the nicotine-chamber, as will be hereinafterexplained.

To enable others to understand myinvention, I will proceed to describeit.

'A represents the bowlof the pipe, and B the stem thereof, both of theordinary or any suitable form or material.

C is a disk or diaphragm, which is perforated, as will be seen byreference to Fig. 2, and which is of a size that will allow itsinsertion in the bowl of the pipe. To this diaphragm there is attached atube, a, which extends through the bottom of the pipe. On thelower endof this tube a a screw-thread, b, is cut, on which is screwed thenicotine-chamber D.

There is a space, I), left between the bottom surface of the bowl andthe diaphragm for the reception of the nicotine and other poisonousmatters as they fall through the perforations in the diaphragm 5 andholes 0 are cut through the tube to allow the nicotine, 850., in thebottom of the bowl to pass down into the nicotinechamber D through thesaid tube.

By this arrangement I obtain all the advantages of a pipe provided witha nicotine-chamber, and at a much less expense than with such pipes asordinarily constructed, for the reason that the parts can be-morecheaply made, little accuracy in their fitting being required. Again,unless all the parts in a pipe where the smoke is made to pass through anicotinechamber in order to deposit its poisonous matters are kept veryclean, the smoke is more or less impregnated with the disagreeable odorof these parts, which creates a nauseating effect upon the smoker; butby my arrangement the smoke in its passage from the bowl of the pipe tothe mouth does not come in contact with the nicotine chamber, only withthe disk or diaphragm. The diaphragmis so arranged that the smoke mustcome in contact with it before passing to the stem of the pipe, and thiscontact with a metallic surface cools the smoke,

and therefore causes it to depositnicotine and other poisonous matters,which readily run through the diaphragm down into the nicotinechamber.Again, the parts can all be cleaned very quickly, it being onlynecessary to unscrew the nicotine-chamber, when the diaphragm and tubewill fall out of the bowl of the pipe upon reversing the same, and thusthese two parts (the nicotine chamber and diaphragm, with its tubeattached) are the only ones that will need cleaning. Again, the draft ofthe pipe is in no way interfered with; but where the smoke is caused topass through a nicotine-chamber it oftentimes is.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. The disk or diaphragm 0, arranged in the bowl of the pipe below thesmoke-passage, substantially as specified.

2. The combination of the tube a and diaphragm O with the bowl A andnicotine-chamber D, substantially as shown and described.

The above specification of my invention signed by me this 1st day ofJuly, 1865.

EDWIN HOYT.
